Although he’s certainly not short on cash, IKEA founder and multi-billionaire Ingvar Kamprad has admitted he buys most of his clothes at flea markets.

Kamprad, who turns 90 on March 30, is known for being frugal, particularly when it comes to IKEA’s taxes, but in a new documentary being broadcast in his home country of Sweden, he admits that he’s also not too keen on handing over too much for his clothing.

“I don't think I'm wearing anything that wasn't bought at a flea market. It means that I want to set a good example,” he told Swedish channel TV4, The Local reports.

Although Bloomberg ranked Kamprad as the ninth richest man in the world with a worth of $41.2 billion, Kamprad says it is “in the nature of Smaland to be thrifty,” referring to region where IKEA’s first store was opened in 1943.

Only last month, the furniture company was accused of evading over €1 billion ($1.1bn) in taxes between 2009 and 2014 in the EU.

The Green Party issued a report to the European Parliament which outlined how IKEA’s “convoluted corporate structure” was designed to facilitate profit-sharing and tax avoidance “on a grand scale.”

The report shows how the company’s structures basically mean it pays royalties to itself to reduce overall taxation and from 1991 to 2014 managed to avoid paying tax on 84 percent of the €14.3 billion ($16 bn) in royalty income by using Dutch based conduit company.

The report detailed its belief that the revenue was channeled to the Interogo Foundation which is based in Liechtenstein, a well known tax haven.

Interogo Foundation is, as IKEA states on its website, “the ultimate owner of Inter IKEA Group, including Inter IKEA Systems B.V., the worldwide IKEA franchisor and owner of the IKEA Concept.”

IKEA denied the report’s allegations of dodging tax, stating that the group “pays taxes in accordance with laws and regulations, wherever we are present,” adding that the manage their operations “in a responsible way.”
